The National Youth Service Corps (NYSC) has warned that its personnel are going tough to ensure that only those who are duly qualified are eventually mobilised for the programme. The NYSC Director-General, Brig Gen YD Ahmed, said this, according to a press statement issued on Thursday by Eddy Megwa, the NYSC Director, Press and Public Relations, stating that the scheme was committed to prosecuting any unqualified individuals caught during registration.
